User producer interaction in context

User producer interaction (UPI) increases chances for successful innovations. It is not always clear, however, what type of interaction is necessary in a particular context. This article identifies seven different types of UPI: constructing linkages, broadening, characterizing users, upstream involvement, first user enrollment, feedback, and downstream innovation. Specific contextual dimensions from which these UPI types derive relevance are discussed. The technological dimension of this context is conceptualized based on a distinction between types of technologies that differ in the degree to which they are customizable to user demands. Four case studies show that technological characteristics indeed matter for UPI, as do the heterogeneity of users and the phase of technology development.     

Global compliance with international accounting education guidelines

The International Accounting Education Guidelines (IAEG) of the International Federation of Accountants (IFAC) issued since 1982 specify the components for the Professional preparation to become a qualified accountant.

This paper presents the results of a survey of compliance conducted in fifty-four countries outside the USA with International Accounting Education Guidelines (IAEG), as issued by the International Federation of Accountants (IFAC). Its purpose is to provide a benchmark measure of compliance for current assessment of accounting education, and for reference in future studies. This study is the first attempt to examine compliance with IAEGs in all sectors of the world in which IFAC has members. The paper is divided into the following sections: international accounting education guidelines; survey questions; methodology; results; effectiveness of the guidelines, and summary and conclusions.     

Remittances,Monetary Policy,and Partial Sterilization

Remittances play a large and important role in certain economies, where they became a significant share of GDP. Official government records of these flows have been systematically improved since governments realized their importance, but a significant percentage of remittances remain unrecorded. This, together with the shadow economy, may pose a problem for monetary policy. This article uses a limited participation model to examine the differential effect that higher shares of remittances can have on monetary policy and describes the impact of remittances on a small open economy under partial sterilization. It demonstrates how a typical monetary shock will lead to a more pronounced liquidity effect when remittances become a higher proportion of GDP. It also shows that a positive remittance shock improves consumption and lowers interest rates, but as it also reduces work effort it momentarily lowers output. Such dynamics are exacerbated as the degree of partial sterilization is accentuated.     

Grocery shopping and an ageing population: research note

This study focuses on grocery shopping and an ageing population. It hypothesizes that as a population ages so there will be a change in preferences for certain service and product factors associated with grocery shopping. Survey responses were collected from 393 people and the results confirmed the expectations. To analyse the data, a multiplicative determinance model was used. The study concludes with a discussion of the implications of the findings for retailers.     

Spectral Analysis of Advertising-Sales Interaction: An Illustration

Abstract

Cross-spectral analysis is recognized as a powerful analytical tool for the analysis of time-varying behavior in a number of disciplines. Applications in business have been limited, however, and the potential usefulness of this new approach to time series analysis has received relatively little attention in advertising. The purpose of this paper is to explain cross-spectral analysis and illustrate the use of this new technique in studying the interaction between advertising and sales.     

Worktime Demands and Work-Family Interference: Does Worktime Control Buffer the Adverse Effects of High Demands?

This study examined whether worktime control buffered the impact of worktime demands on work–family interference (WFI), using data from 2,377 workers from various sectors of industry in The Netherlands. We distinguished among three types of worktime demands: time spent on work according to one’s contract (contractual hours), the number of hours spent on overtime work (overtime hours), and the number of hours spent on commuting (commuting hours). Regarding worktime control, a distinction was made between having control over days off and vacations (leave control) and having control over starting and finishing times (flextime). These three worktime demands were expected to have separate as well as joint effects on WFI, whereas worktime control should buffer these adverse effects of worktime demands on WFI. Stepwise regression analyses showed that working high numbers of contractual and overtime hours was indeed associated with high WFI. Further, worktime control indeed made a difference in terms of WFI: whereas leave control contributed directly to lower WFI, flextime buffered the adverse effects of long contractual workhours. Our results suggest that very long working days should be prevented, and that worktime control may be a powerful tool to help workers maintaining a good work–family balance.     

Brinksmanship Redux: Employee Assistance Programs’ Precursors and Prospects

Originating in the U.S. 70 years ago as industrial alcoholism programs, and promoted for decades by R. Brinkley “Brink” Smithers, these programs finally gained popularity during the 1970s and 1980s, when they were renamed “employee assistance programs” and given a broader mission than identifying alcoholics. Attempting to change their image as instruments of coercion, EAPs added a variety of social work functions to their portfolios but, now primarily operating as external contractors, have seen cash flows fall dramatically in the face of intense competition from similar services. EAP practitioners have called for restoring the approach promoted by academics supported by Smithers, who aggressively maintain that eliminating behavioral health problems is the responsibility of employees rather than employers. This article compares the evidence addressing the efficacy of that approach with that of alternatives, being developed outside of the U.S., that expand employee rights.     

Minimum variance cross hedging under mean‐reverting spreads,stochastic convenience yields,and jumps: Application to the airline industry

Exchange traded futures contracts often are not written on the specific asset that is a source of risk to a firm. The firm may attempt to manage this risk using futures contracts written on a related asset. This cross hedge exposes the firm to a new risk, the spread between the asset underlying the futures contract and the asset that the firm wants to hedge. Using the specific case of the airline industry as motivation, we derive the minimum variance cross hedge assuming a two‐factor diffusion model for the underlying asset and a stochastic, mean‐reverting spread. The result is a time‐varying hedge ratio that can be applied to any hedging horizon. We also consider the effect of jumps in the underlying asset. We use simulations and empirical tests of crude oil, jet fuel cross hedges to demonstrate the hedging effectiveness of the model. © 2009 Wiley Periodicals, Inc. Jrl Fut Mark 29:736–756, 2009
